Exp(B) Table B4 Binomial logistic event history analyses of stopping a sport and ending a sport club membership in young adulthood (age 18 to 35); Sensitivity analyses in which the four major life events were added separately Source: SportersMonitor 2010 (N = 2272) +p<0.10; *p<0.05; **p<0.01; ***p<0.001 ( two-tailed) a We examined the influence of each major life event in a separate analysis, in which we controlled for gender, age, period, educational level, migration background, participation duration number of sports, intrinsic motivation and sport participation in childhood, but not for the influence of the other major life events. This resulted in multiple estimates for the controls and other statistics (i.e., the constant, the model Chi-square and the Nagelkerke R square), which are therefore not presented in the table. bThis effect (b) was similar but not statistically significant (p>0.10), when the major life events were analysed simultaneously (i.e., in one model, including all events and control variables, as presented in chapter 3; see table 3.2) Appendix
